[xubuntu-users] I cannot install printer - xubuntu 23.10

[Alessandro Lin]

Hello,

*I can't install an hp printer*. My operating system is xubuntu 23.10

The hp instructions say to download and run this command : 'sh 
hplip-3.23.12.run'

Unfortunately I get an error message :
INSTALL MISSING REQUIRED DEPENDENCIES

I installed numerous dependencies, in the end this remains:
INSTALL MISSING REQUIRED DEPENDENCIES
-------------------------------------
*warning: Missing REQUIRED dependency: python3-pyqt4 (PyQt 4- Qt 
interface for Python (for Qt version 4.x))*
warning: This installer cannot install 'python3-pyqt4' for your 
distro/OS and/or version.
error: Installation cannot continue without this dependency. Please 
manually install this dependency and re-run this installer.

After a few unsuccessful attempts I tried with ppa: rock-core / qt4 
which could contain the required package.
*But I still get an error, invalid repository :*
$ sudo apt-get install -t ppa:rock-core/qt4 libqt4-declarative libqt4* 
libqtcore4 libqtgui4 libqtwebkit4 qt4*
Reading package lists... Done
E: The value 'ppa:rock-core/qt4' is invalid for APT::Default-Release as 
such a release is not available in the sources

*I tried:
$ sudo apt install hplip-gui*

Install yes, but it *doesn't work* as it should, error msg:

Unable to open device hp:/usb/DeskJet_2700_series?serial=CN35JFW2RF.
printer may not be connected

I still think I have to install python3-pyqt4 but I don't really know how.

Greetings.
